Not traversing parts of tree. Bug?

[Paul Sargent]

Hi all,

Mercurial freshman, so finger trouble is entirely possible. I'm  
trying to move a small project over to Mercurial, and I'm hitting  
something odd. The system is Mercurial 0.9.4 on Mac OS 10.4.10,  
running on a HFS+ filesystem.

What I'm trying, is to do the initial import of my code, i.e. the  
sequence below.

# hg init
# <setup .hgignore>
# hg addremove
# hg commit

.hgignore looks like this:
---------------------.hgignore --------------------
# use glob syntax.
syntax: glob

*.pyc
*~
*.pch
*~.*
**/build/**
.DS_Store

# switch to regexp syntax.
#syntax: regexp
# ^\.pc/
---------------------.hgignore --------------------

Everything seems to work fine, but it doesn't add part of my tree. In- 
particular it skips two directories called:
./Experiments/Histogram View Test
./Experiments/PaintView

There's a third directory in that area of the tree that works fine.  
It's called:
./Experiments/CIComposite

Performing a 'hg st' doesn't list the files inside the missing  
directories. Neither does 'hg st -i', so it doesn't seem to be  
the .hgignore file (I also moved .hgignore out of the way to make  
sure... no change).

Trying 'hg add ./Experiments/PaintView' does nothing, but 'hg add ./ 
Experiments/PaintView/*' adds the files as expected. Unfortunately,  
although 'hg st' will now see modified files in that directory, new  
files aren't seen.

Any idea what might be going on?

Thanks

Paul
