;doc: cli: add a cheatsheet showing all the main journal syntax

This comes from a review of journal syntax, in preparation for
supporting more Ledger syntax. I think these are the most important
syntax features to teach. See next commit for a corresponding cleanup
of the docs.

# Journal
hledger's default file format, representing a General Journal.
Here's a cheatsheet/mini-tutorial,
or you can skip ahead to [About journal format](#about-journal-format).
## Journal cheatsheet
<!-- keep synced with hledger/test/ledger-compat/syntax/supported.test -->
```journal
# Here is the main syntax of hledger's journal format
# (omitting extra Ledger compatibility syntax).
# hledger journals contain comments, directives, and transactions, in any order:
###############################################################################
# 1. Comment lines are for notes or temporarily disabling things.
# They begin with #, ;, or a line containing the word "comment".
# hash comment line
; semicolon comment line
comment
These lines
are commented.
end comment
# Some but not all hledger entries can have same-line comments attached to them,
# from ; (semicolon) to end of line.
###############################################################################
# 2. Directives modify parsing or reports in some way.
# They begin with a word or letter (or ~ or =).
account actifs ; type:A, declare an account that is an Asset. 2+ spaces before ;.
account passifs ; type:L, declare an account that is a Liability, and so on.. (ALERX)
alias chkg = assets:checking
commodity $0.00
D $0.00

payee Whole Foods
P 2022-01-01 AAAA $1.40
Y 2022

~ monthly
###############################################################################
# 3. Transactions are what it's all about; they are dated events,
# usually describing movements of money.
# They begin with a date.
# DATE DESCRIPTION ; This is a transaction comment.
# ACCOUNT NAME 1 AMOUNT1 ; <- posting 1. This is a posting comment.
# ACCOUNT NAME 2 AMOUNT2 ; <- posting 2. Postings must be idented.
# ; ^^ At least 2 spaces between account and amount.
# ... ; Any number of postings is allowed. The amounts must balance (sum to 0).
2022-01-01 opening balances are declared this way
assets:checking $1000 ; Account names can be anything. lower case is easy to type.
assets:savings $1000 ; assets, liabilities, equity, revenues, expenses are common.
assets:cash:wallet $100 ; : indicates subaccounts.
liabilities:credit card $-200 ; liabilities, equity, revenues balances are usually negative.
equity ; One amount can be left blank; $-1900 is inferred here.
2022-04-15 * (#12345) pay taxes
; There can be a ! or * after the date meaning "pending" or "cleared".
; There can be a transaction code (text in parentheses) after the date/status.
; Amounts' sign represents direction of flow, or credit/debit:
assets:checking $-500 ; minus means removed from this account (credit)
expenses:tax:us:2021 $500 ; plus means added to this account (debit)
; revenue/expense categories are also "accounts"
2022-01-01 Whole Foods | payee name and description can be separated by a pipe char
; Transaction or posting comments can contain searchable tags,
; written NAME: or NAME:VALUE (value ends at comma or end of line).
; Here's tag1:with a value, and an empty tag2:
; A few tags have special meaning. A "date:" tag on a posting adjusts its date.
assets:checking $-50 ; date:2022-01-03, checking cleared two days later
expenses:food
2022-01-01 ; The description is optional.
; Any currency/commodity symbols are allowed, on either side.

assets:gringotts -10 gold
assets:pouch 10 gold
revenues:gifts -2 "Liquorice Wands" ; Symbols containing unusual characters
assets:bag 2 "Liquorice Wands" ; must be double-quoted.

assets:investments 2.0 AAAA @ $1.50 ; @ means per-unit cost
assets:investments 3.0 AAAA @@ $4 ; @@ means total cost
assets:checking $-7.00
2022-01-02 assert balances
; Balances can be asserted for extra error checking, in any transaction.
assets:investments 0 AAAA = 5.0 AAAA
assets:pouch 0 gold = 10 gold
assets:savings $0 = $1000
1999-12-31 Ordering transactions by date is recommended but not required.
; Postings are not required.

2022/1/1 formats are
12/31 also allowed (but consistent YYYY-MM-DD is recommended).

## About journal format
hledger's usual data source is a plain text file containing journal entries in hledger journal format.
This file represents a standard accounting [general journal](http://en.wikipedia.org/wiki/General_journal).
