Bug #4496: ri can't describe Kernel.warn

Target version: 
ruby -v: ruby 1.8.7 (2010-06-23 patchlevel 299) [x86_64-linux] 


It appears to be impossible to read documentation on Kernel.warn, due to overlapping matches.

$ ruby -v
ruby 1.8.7 (2010-06-23 patchlevel 299) [x86_64-linux]
$ ri 'Kernel.warn' | cat
More than one method matched your request. You can refine
your search by asking for information on one of:

     Kernel#warn, Kernel#with_warnings, Kernel#enable_warnings,
     Kernel#silence_warnings, Kernel#suppress_warnings, Kernel#warn
$ ri 'Kernel#warn' | cat

     Kernel#warn, Kernel#with_warnings, Kernel#enable_warnings,
     Kernel#silence_warnings, Kernel#suppress_warnings, Kernel#warn
$ ri 'Kernel::warn' | cat
Nothing known about Kernel::warn

Suggested solution: if your search term is an exact match, then display it (don't search for other possible matches)
