'git column's '--nl' option can be used to specify a "string to be
printed at the end of each line" (quoting the man page), but this
option and its mandatory argument has been parsed as OPT_INTEGER since
the introduction of the command in 7e29b8254f (Add column layout
skeleton and git-column, 2012-04-21). Consequently, any non-number
argument is rejected by parse-options, and any number other than 0
leads to segfault:
$ printf "%s\n" one two |git column --mode=plain --nl=foo
error: option `nl' expects a numerical value
$ printf "%s\n" one two |git column --mode=plain --nl=42
Segmentation fault (core dumped)
$ printf "%s\n" one two |git column --mode=plain --nl=0
one
two
Parse this option as OPT_STRING.
