[GRASS5] Re: [GRASSLIST:4462] fixes for recent problems in tcltkgrass for GRASS 5.3

[Michael Barton]

Sorry if I misstated this. I was working from memory, not finding the
original email that described what happened.

Prior to an update to (what I understood was) one of the parsing routines by
Hamish in late July or August, a command in a GRASS 5.3 tcltkgrass module
like {d.measure -s} would parse as a single string...

d.measure -s 

After that update, this now parses seems to parse (incorrectly) as a list...

d.measure
-s

Possibly I misunderstood which update was the likely cause of this, but the
discussions I saw suggested that it was one of the updates that allowed
GRASS 5.7 to correctly parse strings that included spaces.

If this is not the case, then perhaps it is worthwhile to dig more to track
it down. Perhaps similar, but not quite equivalent changes were made to the
parsing routines of 5.3 and 5.7 at the same time???
