photo. Use the short keyid as the filename on 8.3 systems.
* exec.h, exec.c (make_tempdir, exec_write, exec_finish): Allow caller to
specify filename. This should make things easier on windows and macs
where the file extension is required, but a whole filename is even better.
* keyedit.c (show_key_with_all_names, show_prefs): Show proper prefs for a
v4 key uid with no selfsig at all.
* misc.c (check_permissions): Don't check permissions on non-normal files
(pipes, character devices, etc.)
let a key conflict (same keyid but different key) stop the import: just
skip the bad key and continue.
* exec.c (make_tempdir): Under Win32, don't try environment variables for
temp directories - GetTempDir tries environment variables internally, and
it's better not to second-guess it in case MS adds some sort of temp dir
handling to Windows at some point.
* misc.c (pct_expando): %t means extension, not name ("jpg", not "jpeg").
* keyserver.c (keyserver_spawn), photoid.c (show_photos), exec.h, exec.c:
Allow the caller to determine the temp file extension when starting an
exec_write and change all callers.
execution. --disable-exec implies --disable-ldap and --disable-mailto.
Also look in /usr/lib for sendmail. If sendmail is not found, do not
default - just fail.
* exec.c: Provide stubs for exec_ functions when NO_EXEC is defined.
When key signing with multiple keys at the same time, make sure each key
gets the sigclass prompt
Close the iobuf and FILE before trying to reap the child process to
encourage the child to exit
Disable cache-on-close of the fd iobuf (shouldn't all fd iobufs not be
cached?)
