Subject: Wrap the text of error messages
X-Git-Tag: v0.15-rc1~217^2~1
X-Git-Url: https://www.chiark.greenend.org.uk/ucgi/~mdw/git/stgit/commitdiff_plain/a4b511ffeaba7e283d079d67d76e15463a54062e?ds=inline

Wrap the text of error messages

... so that they fit nicely in an 80-column terminal. This makes it
unnecessary to embed newlines and extra spaces in a few places.

This patch only wraps the text of tagged output messages. I haven't
found a reason to wrap other messages, but I haven't looked long and
hard.
