Subject: Dgit.pm: printdebug: Strip empty strings from @_ and maybe quit early
X-Git-Tag: archive/debian/6.7~142
X-Git-Url: https://www.chiark.greenend.org.uk/ucgi/~ianmdlvl/git?p=dgit.git;a=commitdiff_plain;h=8047fa8b32e744b4033cdbe451108fdb2ea0e505;hp=38e68231e64477cc87c3e899c6f547c62ec590e9

Dgit.pm: printdebug: Strip empty strings from @_ and maybe quit early

Now the meat of the function always has nonempty $_[-1].
