* passphrase.c: Don't check for __CYGWIN__, so it is treated as a
unix-like system.
* options.h, g10.c (main), textfilter.c (standard): Use new option
--rfc2440-text to determine whether to filter "<space>\t\r\n" or just
"\r\n" before canonicalizing text line endings. Default to
"<space>\t\r\n".
(not used). (standard): 2440 says that textmode hashes should canonicalize
line endings to CRLF and remove spaces and tabs. 2440bis-12 says to just
canonicalize to CRLF. So, we default to the 2440bis-12 behavior, but
revert to the strict 2440 behavior if the user specifies --rfc2440. In
practical terms this makes no difference to any signatures in the real
world except for a textmode detached signature.
getkey.c, keydb.c, openfile.c, plaintext.c, status.c, gpgv.c, keygen.c,
options.h, sig-check.c, tdbio.h, encode.c, mainproc.c, parse-packet.c,
signal.c, textfilter.c: Edit all preprocessor instructions to remove
whitespace before the '#'. This is not required by C89, but there are some
compilers out there that don't like it.
