;add: allow older haskeline again, it's needed for stackage (reopens [#2410])

For now, `hledger add` with the stackage build of hledger 1.51.2+ will once again show ANSI junk.
Dev builds, the github release binaries, stackage builds of hledger-1.50..1.51.1,
and stackage hledger builds in future snapshots with a GHC that provides the fixed haskeline,
will remain free of that bug.

   It does not do this; we assume that if you are using a `D` directive
   you prefer not to see the commodity symbol repeated on amounts in the journal.
 - `add` creates entries in journal format; it won't work with timeclock or timedot files.
+- There is a known issue on Windows if this hledger version is built from stackage: the prompts will show ANSI junk instead of colours (#2410).
+  You can avoid this by using official hledger release binaries or by building it with haskeline >=0.8.4;
+  or by running `add` with `--color=no`, perhaps configured in your config file.
