Subject: [PATCH] strbuf_add_lines(): avoid SP-HT sequence
The strbuf_add_commented_lines() function passes a pair of prefixes,
one for a line that has some meat on it, and the other for an empty
line. The former is set to a comment char followed by a SP, while
the latter is set to just the comment char. This is to give a SP
after the comment character, e.g. "# <user text>\n" and to avoid
emitting an unsightly "# \n" in its output.
Teach the machinery to also use the latter space-less prefix when
the payload line begins with a tab; otherwise we will end up showing
"# \t<user text>\n" which is similarly unsightly.
