What would be nice is something like v.touch/v.comments to add text from
stdin or a file into the 'v.info -h' history. It is often useful to
write some notes down somewhere.

As for r.support, it needs to be rewritten, IMO. It's pretty much
unusable in 5.7 without at minimum adding a title="" command line option.
As Glynn noted, the raster 'hist' comments are fairly limited in size
and you need to use struct History;G_short_history();G_write_history()
which pretty much limits you to C modules during initial map creation.
(and I thought it was 80cols x 40lines? shrug)
