I know tchan will think I'm crazy and probably think it's pointless, but I'm 
gunna submit it anyway because I'm anal like that :o) Anyhow... if you do a 
'lvu newer/older X' and let X be anything other than a number that falls in 
the predefined range in the newer() and older() function you get a infinate 
loop of something like "/bin/lvu: line 320: [: JUNKVALUE: integer expression 
expected", that you have to Ctrl+C out of.  Below is a patch to fix that.  
This was against theedge dated 20040416.
