check-code: grep's context flags don't need an extra space before number
A bit of useless trivia found while researching this: OpenBSD's grep's -C has a
default value (of 2) and disallows space before the argument (while -A and -B
allow).
fixbundle() {
grep -v 'saving bundle' | grep -v 'saved backup' | \
grep -v added | grep -v adding | \
grep -v "unable to find 'e' for patching" | \
grep -v "e: No such file or directory" | \
cat
}
