Space Character Causes Problem

Here is a quote from the README.txt file of this module.

2. go to admin/settings/blocktheme and add entries like:
customtemplate|My Custom Template
mysupertemplate|My SuperTemplate
Where the first name is the machine-readable etc...

This implies, correctly, that a space character ought not to be present between the "customtemplate" and the "|" character (in the above example). However, it is not explicitly mentioned anywhere in the documentation, and certainly not in the readme.txt file itself. But actually, having a space character after the machine readable name and before the | character causes this module to malfunction.
