Subject: Wrap strings in _() if they need translation.
X-Git-Tag: BISON-1_49b~14
X-Git-Url: https://git.saurik.com/bison.git/commitdiff_plain/db2cc12fd07acb54b19cf6475f6d330a8b904e0a

Wrap strings in _() if they need translation.

Use strings rather than escapes when possible,
to minimize the number of warnings from xgettext.

(handle_action_dollar, handle_action_at): Don't use isdigit,
as it mishandles negative chars and it may not work as expected
outside the C locale.
