Subject: [PATCH] Fix bug reported by Jan Macku: alias postcmd '/bin/echo
|
||||
-n "COMMAND:"'"'"'\!#:-$:gx'"'"'' echo 1 2 3 4 5 ^P prints echo 1
|
||||
2 3 4 Reason: domod() enters junk history entries with event number
|
||||
HIST_PURGE aliasrun which is used to run postcmd modifies the history
|
||||
appending those entries. Fix by explicitly cleaning up those entries in
|
||||
aliasrun
