"r.info -e" output not compliant with eval

[andbal]

I've got an error using the command eval `r.info -e <map_name>`. This is the output:

GRASS 7.1.svn (---):~ > eval `r.info -e map=soilheatflux.dos4`
bash: unexpected EOF while looking for matching `"'
bash: syntax error: unexpected end of file

The error is likely to be correlated to the flags -e because with other flag (like -r for example), the command eval works well.

I add the output of r.info -e executed outside eval

GRASS 7.1.svn (L5_Papk):~ > r.info -e map=soilheatflux.dos4 
map=soilheatflux.dos4

Another person suggest me that maybe is a quotes problem in the comments field.

Replying to andbal:

I add the output of r.info -e executed outside eval

...
comments="i.eb.soilheatflux albedo="albedo.dos4" ndvi="ndvi.dos4" temperature=\"toa_temp.6" netradiation="rad.M1" localutctime="overpass_utc" outpu\t="soilheatflux.dos4""

The issue is that the inner quotes " need to be escaped when fprintf'ing the comment:

I suppose that there is already a function for that?
