another docs problem - imp

[cito at online.de (Christoph Zwerschke)]

I assume one cause of the misunderstanding was the name "path" for the 
search path. If it had been named "paths" it would have been more 
obvious. But Python is only following a common standard here. Since 
environment variables are called PATH, CLASSPATH etc. it was only 
logical to use PYTHONPATH and sys.path etc. Therefore the imp module 
uses "pathname" where it is only a single path.

Probably the people who once invented the env variables didn't care 
about writing PATHS because it sounds like PATH anyway (or is there a 
difference? I am German).

Anyway, the docs are technically correct. Maybe the best solution would 
not to improve the docs but to allow path to be a string in which case 
it would be treated as [string].
