Hmm... I know it has limitations, but I haven't heard of problems with it linked to issues such as cygwin file names being confused as remote file names. >> AFAIK jka-compr.el works fine. > Because it takes great care not to touch anything that changes the > semantics of file names: the file name still behaves the same with and > without jka-compr. By contrast, AFAIU environments cannot do that by > their very nature. I think environments implemented via file-name-handlers-alist would only affect process-file, start-file-process, and maybe a couple more functions, and wouldn't otherwise "change the semantics of file names" any more than jka-compr.
