[Monotone-devel] [PATCH] fix test "syntax_errors_in_.mtn-ignore"

[Ralf S. Engelschall]

A "make check" on h:n.v.m currently results in one failed test:
"syntax_errors_in_.mtn-ignore". The reasons is because the test performs
a "mtn ls unknown" command and checks the stderr output. Unfortunately,
it doesn't seem to be deterministic in what order the files are checked
against the Lua function ignore_file() and hence the first line ("mtn:
warning: while matching file 'XXXX':") of the stderr output of "mtn ls
unknown" contains an abitrary filename "XXXX" and hence lets the test
fail. There are multiple possibilities to fix this. I propose to simply
skip the first line of stderr during output comparisons:

Any objections?
