+:breaka[dd] expr {expression}
+ Sets a breakpoint, that will break whenever the {expression}
+ evaluates to a different value. Example: >
+ :breakadd expr g:lnum
+
+< Will break, whenever the global variable lnum changes.
+ Note if you watch a |script-variable| this will break
+ when switching scripts, since the script variable is only
+ valid in the script where it has been defined and if that
+ script is called from several other scripts, this will stop
+ whenever that particular variable will become visible or
+ unaccessible again.

The [lnum] is the line number of the breakpoint. Vim will stop at or after
this line. When omitted line 1 is used.
