Feature Request: Fixed-Width Font in "Find what" and "Replace with" Fields

[shirayuki]

I would like to request an enhancement for the "Find" and "Replace" dialogs in WinMerge.

Request:
Please consider using a fixed-width (monospaced) font for the "Find what" and "Replace with" fields, or add an option to change the font.

Reason:
I often need to replace tab characters with four spaces (or vice versa). However, it's difficult to see exactly how many spaces have been entered in these fields with a proportional font. A fixed-width font would make it much easier to visually distinguish the number of spaces entered, improving accuracy and usability.

In commit 8d5b2dc we changed it to use the fixed-width font currently used in the editor.
