Maybe I'm doing it wrong, or maybe it's the intended behaviour,
but I find that a trailing whitespace after a pattern in .gitignore
makes the pattern void with git 1.8.1.5.
I doubt we do anything clever like that.
$ git init
$ touch hello.o "hello.o " "hello.o " hello.c
$ echo "*.o " >.gitignore
$ git status | cat -e
# On branch master$
#$
# Initial commit$
#$
# Untracked files:$
# (use "git add <file>..." to include in what will be committed)$
#$
# .gitignore$
# hello.c$
# hello.o$
# hello.o $
nothing added to commit but untracked files present (use "git add" to track)$
The user tells to ignore anything followed by a dot followed by a
lowercase Oh followed by a SP. We ignore "hello. ", but not "hello.o"
nor "hello.o " (two SPs at the end), just as told.
