--no-ignore-files option for gnulib-tool?

[Karl Berry]

Bruno/all, would you accept a change for an option to avoid updating of
.cvsignore/.gitignore in gnulib-tool?

For purposes of clarity (I hope, anyway), below I merely add the if...fi
with the wrong indentation.  In an actual change all the intervening
code would be "changed" since it would all be indented two more spaces.
I'd put something into the doc too.

Thanks,
Karl

        * gnulib-tool: --no-ignore-files: new option.
        (do_ignore_files): new variable, true by default.
        (func_import): conditionalize updating of .cvsignore/.gitignore.
