Re: [PATCH] Fix whitespace in "help set inferior-tty"

[Philippe Waroquiers <philippe.waroquiers@skynet.be>]

Note that gdb/unittests/command-def-selftests.c checks various invariants about the
command doc strings.
We might add there a new invariant that there is no white space before a LF
and no space at the end of doc string.

This should avoid such problems to re-appear in the future.

Thanks

Philippe
