* FILEPKG: EDITCALLERS now notices possible new stream after getting filemap
* GITFNS: cdw and cdg commands preserve pseudohost
* SAMEDIR: match all combinations of truefilename and pseudofilename
* PSEUDOHOSTS: Bug fix--openstream failure goes thru normal error machinery
* ADIR: Put in stubs for TRUEFILENAME, PSEUDOFILENAME, PSEUDOHOSTP
Also, fix \COPYSYS so it works with pseudhosts
* PSEUDOHOSTS: GETHOSTINFO of pseudohost goes to true host
* CMLPATHNAME: Remove unused PARSE-NAMESTRING1
Avoid stumbling on it in future maintenance. Also, remake filemap for functions and defmacros
* SAMEDIR, COMPAREDIRECTORIES: FILENAMEFIELD → FILENAMEFIELD.STRING
in a few places. No need to hash atoms
* LLCHAR: expose $$READONLY in inpname I.s.opr
* GITFNS: prc menu shows superset relations
* GITFNS: Sort the prc menu
* EDITINTERFACE: Better edit-date management
* PRETTYFILEINDEX: Destination can be any imagestream, not just display
* TEDIT-PF-SEE: Use SEE instead of COPYTO IMAGESTREAM
to get better formatting of PRETTYFILEINDEX
