Recenty I created a multi-line branch description with '.' and '='
characters on one of the lines, and noticed that fragments of that line
show up when completing set variable names for 'git config', e.g.:
$ git config --get branch.b.description
Branch description to fool the completion script with a
second line containing dot . and equals = characters.
$ git config --unset <TAB>
...
second line containing dot . and equals
...
The completion script runs 'git config --list' and processes its output to
strip the values and keep only the variable names. It does so by looking
for lines containing '.' and '=' and outputting everything before the '=',
which was fooled by my multi-line branch description.
A similar issue exists with aliases and pretty format aliases with
multi-line values, but in that case 'git config --get-regexp' is run and
subsequent lines don't have to contain either '.' or '=' to fool the
completion script.
Though 'git config' can produce null-terminated output for newline-safe
parsing, that's of no use in this case, becase we can't cope with nulls in
the shell.
Help the completion script by introducing the '--list-names' and
'--get-names-regexp' options, the "names-only" equivalents of '--list' and
'--get-regexp', so it doesn't have to separate variable names from their
values anymore.
