/* mondo-rstr-newt.c               Hugo Rabson


07/12
- wider mountlist entry editor window

03/28/2004
- removed g_mountlist_fname

07/02/2003
- fixed calls to popup_and_get_string()

06/05
- cleaned up get_isodir_info()

05/02
- added strip_path() to improve file list display for long paths (Conor)

04/24
- added lots of assert()'s and log_OS_error()'s

04/08/2003
- commented out call to sort_mountlist_by_device(), just in case it's 
  futzing with LVM/RAID users

08/21/2002
- fix MOUNTLIST_FNAME and RAIDTAB_FNAME if Reload button finds them empty

08/19
- fixed what_number_cd_is_this() to take bkpinfo as parameter

07/01 - 07/31
- renamed from mondo-newt.c to mondo-rstr-newt.c
- moved lots of subroutines to libmondo-newt.c
- added hooks to libmondo
- better handling of yes/no/YES/NO
- better "% done" feedback (Philippe de Muyter)

05/01 - 06/30
- trim trailing \n from fgets() in a couple of functions
- expanded "May I write mountlist?" message
- replace scanf() with a properly restricted fgets() (Troff)

02/01 - 02/28/2002
- allow up to 50 chars in popup_and_get_string()'s input field
- if g_current_progress > g_maximum_progress then g_current_progress=g_max...
  to stop the progress bar from shooting off the RHS of the screen :)
- beefed up the RAID-related logging a bit
- don't complain if partition format is a number (1-255)
- if hard disk does not exist then warn user when editing mountlist
- when running 'eject -t', log its output

[...]

08/09/2001
