* TEDIT, TEXTOFD: Pass FORMAT in PROPS to OPENSTREAM
In TEDIT and OPENTEXTSTREAM. I don't think TEDIT interprets the external format, but at least the info is there
* WINDOW: CREATEW prompts on one line
It was calling PROMPTPRINT twice, which resulted in orphan-looking lines
* EXAMINEDEFS: Propagate textwidth to COMPARETEXT
* COMPARETEXT: propagate height/width of text windows, for linelength
#800
* GREP: Will work with external formats, after FILEPOS update
Line printout could be better, if e.g. it is a Lisp source file, but...
* EXAMINEDEFS: Propagate window width to COMPARETEXT, for LINELENGTH
* GITFNS: added fetch before git log
* PSEUDOHOSTS: Pseudohost-streams are now registered on the PH device, not the target device
* EXTERNALFORMAT, XCCS: Globalvar declaration in wrong place
Also updated \CHECKEOLC macro
* GITFNS: moved git fetch to beginning of prc
* GREP: Propagated OUTSTREAM
Also, STREAM can be given as the format argument to \EXTERNALFORMAT, gets the stream's format.
Atoms (LF, CR, CRLF, ANY) allowed for EOL specs (caller won't need exports.all)
