60
6104/27
62- don't echo (...res=%d...) at end of log_it()
63  unnecessarily
64- replace newtFinished() and newtInit() with
65  newtSuspend() and newtResume()
66
6704/24
68- added some assert()'s and log_OS_error()'s

7004/09
71- cleaned up run_program_and_log_output()
72
7304/07
74- cleaned up code a bit
75- let run_program_and_log_output() accept -1 (only log if _no error_)
76
7701/02/2003
78- in eval_call_to_make_ISO(), append output to MONDO_LOGFILE
79  instead of a temporary stderr text file
80
8112/10
82- patch by Heiko Schlittermann to handle % chars in issue.net
83
8411/18
85- if mkisofs in eval_call_to_make_ISO() returns an error then return it,
86  whether ISO was created or not
87
8810/30
89- if mkisofs in eval_call_to_make_ISO() returns an error then find out if
90  the output (ISO) file has been created; if it has then return 0 anyway
91
9208/01 - 09/30
93- run_program_and_log_output() now takes boolean operator to specify
94  whether it will log its activities in the event of _success_
95- system() now includes 2>/dev/null
96- enlarged some tmp[]'s
97- added run_program_and_log_to_screen() and run_program_and_log_output()
