Re: [Groff] win32 experiences?

[Kees Zeelenberg]

It would affect users on non-MS-Windows systems who process files made on 
MS-Windows, i.e. with CR-LF. A perhaps not uncommon example is where text 
files made with an ordinary MS-Windows editor (and thus contain CR-LF's), 
are processed by a Cygwin Groff and where the Cygwin setup is as on Unix 
(i.e. text files have LF as line-endings).
As long as 0xOD is just ignored, its being forbidden would only give lots of 
warnings. If, however, 0x0D would generate an error and a premature stop of 
groff processing, it would be very unpleasant.
BTW, a native MS-Windows build of Groff does not have problems with CR-LF. 
Upon reading, all CR-LF's are converted to LF, and vice versa upon output. 
This happens in the read and write buffers, and so groff will never see the 
CR's.

No idea. I would think that if handling 0x0D as an `invalid_input_char'
hasn't afected the ability of OSX users to process their files it
wouldn't hurt to use in all the preprocessors.
