grep-find bug when compilation-window-height not nil

[Peter Lee]

NOTE: This is a cvs report.. not sure if this is right place for these
or not.

Setting (setq compilation-window-height 15) (or anything other than
nil) seems to cause problems with grep-find's output.

,----
| M-: (setq compilation-window-height 15) RET
| grep-find RET
| Run find (like this): find . -type f -print0 | xargs -0 -e grep -nH -i -e 
"sink_entry.*2011" RET
`----

displays the following:

,----
| cd c:/src/Test/
| find . -type f -print0 | xargs -0 -e grep -nH -i -e "sink_entry.*2011"
| 
| grep finished (matches found) at Tue Sep 09 23:19:39
`----

It claims to have found matches but doesn't display any.

Run same test again but change compilation-window-height to nil.

,----
| M-: (setq compilation-window-height nil) RET
| grep-find RET
| Run find (like this): find . -type f -print0 | xargs -0 -e grep -nH -i -e 
"sink_entry.*2011" RET
`----

correctly yields:

,----
| cd c:/src/Test/
| find . -type f -print0 | xargs -0 -e grep -nH -i -e "sink_entry.*2011"
| Binary file ./Debug/Test.bsc matches
| ./Host.h:49:       SINK_ENTRY_INFO(1, __uuidof(EApplication), 2011, 
OnSlideShowBegin, &OnSlideShowBeginInfo)
| ./Host.h~:48:       SINK_ENTRY_INFO(1, __uuidof(EApplication), 2011, 
OnSlideShowBegin, &OnSlideShowBeginInfo)
|

I tried a few more tests setting compilation-window-height to
different values and it had the same problem using the same regex.

However if I changed the regex such that it had no .* in it, setting
the compilation-window-height to a value didn't break it.

| grep-find RET
| Run find (like this): find . -type f -print0 | xargs -0 -e grep -nH -i -e 
"sink_entry" RET

correctly displayed:
