* mandos.xml (EXAMPLE): Replaced all occurences of command name with
"&COMMANDNAME;".
* plugins.d/password-prompt.c (main): Improved some documentation
strings. Do perror() of
tcgetattr() fails. Add debug
output if interrupted by signal.
Loop over write() instead of
using fwrite() when outputting
password. Add debug output if
getline() returns 0, unless it
was caused by a signal. Add
exit status code to debug
output.
* plugins.d/password-prompt.xml: Changed all single quotes to double
quotes for consistency. Removed
<?xml-stylesheet>.
(ENTITY TIMESTAMP): New. Automatically updated by Emacs time-stamp
by using Emacs local variables.
(/refentry/refentryinfo/title): Changed to "Mandos Manual".
(/refentry/refentryinfo/productname): Changed to "Mandos".
(/refentry/refentryinfo/date): New; set to "&TIMESTAMP;".
(/refentry/refentryinfo/copyright): Split copyright holders.
(/refentry/refnamediv/refpurpose): Improved wording.
(SYNOPSIS): Fix to use correct markup. Add short options.
(DESCRIPTION, OPTIONS): Improved wording.
(OPTIONS): Improved wording. Use more correct markup. Document
short options.
(EXIT STATUS): Add text.
(ENVIRONMENT): Document use of "cryptsource" and "crypttarget".
(FILES): REMOVED.
(BUGS): Add text.
(EXAMPLE): Added some examples.
(SECURITY): Added text.
(SEE ALSO): Remove reference to mandos(8). Add reference to
crypttab(5).
