Subject: Fix a bug with environment variables in the shell

The code to find and replace environment variables was only searching
for alphanumeric characters. This means that the shell was unable to
recognize environment variables that used an underscore, for instance.
This patch allows the underscore character to be used when settings and
reading environment variables.
