As I understand docs if I set CYGWIN=noglob then command line arguments
passed to Cygwin app WITHOUT changes.
I use native Emacs build so worry about stop Cygwin damage passed arguments.
And seems this is not true.
With CYGWIN=noglob all double quotes removed from args!
Originally I discaver this when I call Cygwin application from NT Emacs by:
(call-process "bash" nil t nil "-c" " echo \"a b\" ")
I get: a b (ONE space!)
I wrote simple app that print its args quoted:
(call-process "printarg" nil t nil "-c" "echo \"a \"\"\"\" b\"\"\"\"\"")
"/cygdrive/d/home/usr/bin/printarg"
"-c"
"echo a b"
If compile printarg.c with MSVC all quotes printed:
(call-process "printarg" nil t nil "-c" "echo \"a \"\"\"\" b\"\"\"\"\"")
"/cygdrive/d/home/usr/bin/printarg"
"-c"
"echo "a """" b""""""
Same happen with cmd.exe:
cmd# printarg-msvc "a \" b"
"printarg-msvc.exe"
"a " b"
cmd# set CYGWIN=glob
cmd# printarg-cygwin "a \" b"
"printarg"
"a " b"
cmd# set CYGWIN=noglob
cmd# printarg-cygwin "a \" b"
"printarg"
"a \"
"b"
