Problem with link highlight/clicking when "_/" appears in path

[jmmerz]

I've noticed a problem in Mintty 3.6.4 with link highlighting and clicking when the string _/ (an underscore followed by a slash) appears in the URL or filesystem path.

To reproduce:

1. Paste the string https://www.example.com/this_/url/fails into the terminal.
2. Hold the Control key and hover the mouse pointer over a point in the URL after the _/ (i.e. url/fails segment).

Actual behavior:

• When hovering, only /url/fails is highlighted.
• When I click on it, Mintty attempts to open the local directory /url/fails

Expected behavior:

• When hovering, the entire URL should be highlighted.
• When clicked, the entire URL https://www.example.com/this_/url/fails should be opened.

The same behavior occurs if _/ appears in a local filesystem path. I'm keeping this report concise, but am happy to provide an example with local file paths if desired.

Workaround:

If I hover the mouse over a point in the URL before any instance of _/ both highlight and clicking work as expected.

Other info

• This works as expected in Mintty 3.6.3.
• I have not examined the code, but I suspect this may be related to the recent changes in URLs with parentheses are not clickable #1196 to enable clicking URLs with parentheses.
• I'm using Mintty with Cygwin version 3.4.6-1 on Windows 10. (All recent Windows patches applied and I did a full update of Cygwin modules/dependencies/etc a few days ago).

This appears to be fixed in the current repository version already.

Thanks, just built from sources and verified it works.

Apologies for the noise, closing this issue now.
