Closed issue by msiism on void-packages repository

https://github.com/void-linux/void-packages/issues/25285

Description:

### System

* xuname: 
 ``Void 5.8.13_1 x86_64 GenuineIntel uptodate rF``
* package:  
``tcl-8.6.10_2``

### Problem description

Running ``man 3tcl expr``, ``man 3tcl file``, or ``man 3tcl join`` should turn up the manual page for the respective Tcl command, just as, e.g., running ``man 3tcl clock`` would.

But it doesn't. Instead, I get the manual pages for expr(1), file(1), and join(1), respectively.

Further testing suggests that this problem occurs with all Tcl commands that have a command of the same name in section 1 of the manual.
