[R-SIG-Mac] R.app: Up-arrow yields incomplete command recall when # is in a character string

[Steven McKinney]

Something is amiss with the mechanism that
recalls the last command when the user hits
the up-arrow key in the R.app GUI listener:


> formatC(0.0059999, digits=2,format="fg",flag="#")
[1] "0.0060"
> ## Hit the up-arrow to recall last command - 
> ## note that not all of the command appears
> formatC(0.0059999, digits=2,format="fg",flag="


Looks as if some code needs to be added
to differentiate 
# outside of quotes as a comment character 
from 
# inside quotes as a portion of a character string,
which I'll respectfully ask more talented programmers
than myself to fix in their copious spare time,
with many thanks in advance.

It works in a Mac terminal shell R session
