The problem is you're using too many arguments. There are limits on argument lists and variable lengths, and if anything bash is unusually generous. You should keep both below a couple kilobytes in size.

This means statements that slurp in and/or compare entire massive blocks of data, like:

Code:
DILBERTURL=`entirety of everything`
$DILBERTURL != `cat .previouscm.txt | grep $DILBERTURL`

...should be avoided. Save the results directly into files with redirection, then use the diff command to see if there's any changes instead.

ZGREP(1)                                                      General Commands Manual                                                     ZGREP(1)

NAME

       zgrep - search possibly compressed files for a regular expression

SYNOPSIS

       zgrep [ grep_options ] [ -e ] pattern filename...

DESCRIPTION

       Zgrep  invokes  grep  on  compressed  or  gzipped  files.   These  grep  options  will  cause  zgrep  to  terminate  with  an  error  code:
       (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*).  All other options specified are passed directly to grep.  If no file is specified,  then  the
       standard input is decompressed if necessary and fed to grep.  Otherwise the given files are uncompressed if necessary and fed to grep.

       If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.

EXIT CODE

       2 - An option that is not supported was specified.
