New description:

 At time (besides the weird fact that the angle convention of azimuth does
 not match the standard GRASS convention) the easting and northing input
 does not accept sexagesimal input in lat-long location:

 {{{
 GRASS 7.2.0svn (latlong):~ >
 r.plane output=plane dip=45 azimuth=9 \
   easting=0:04:14.5E northing=48:52:14.5N elev=1000 type=CELL
 Traceback (most recent call last):
   File "/home/neteler/software/grass72/dist.x86_64-pc-linux-
 gnu/scripts/r.plane", line 128, in <module>
     main()
   File "/home/neteler/software/grass72/dist.x86_64-pc-linux-
 gnu/scripts/r.plane", line 78, in main
     ea = float(options['easting'])
 ValueError: invalid literal for float(): 0:04:14.5E
 }}}

 AFAIK G_OPT_M_COORDS would support that but here the values have to be
 specified separately.

 Replying to [comment:5 lucadelu]:
 > Please look and try r74438

 Thanks, but now I get

 {{{
 r.plane output=plane dip=45 azimuth=9 easting=0:04:14.5E
 northing=48:52:14.5N elev=1000 type=CELL
 ERROR: Input coordinates seems to be invalid
 }}}

 With debug output added locally, I see that "E" and "N" are the problem
 (which are accepted in g.region, see
 https://grass.osgeo.org/grass76/manuals/g.region.html#changing-extent-and-
 raster-resolution-using-values):

 ValueError: invalid literal for float(): 14.5E

 IMHO float_or_dms() needs an update to accept E and N.
