[PATCH] Replace HTTP links with HTTPS ones: UNICODE SUBSYSTEM

[PATCH] Replace HTTP links with HTTPS ones: UNICODE SUBSYSTEM

[Alexander A. Klimov]

Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.

Deterministic algorithm:
For each file:
  If not .svg:
    For each line:
      If doesn't contain `\bxmlns\b`:
        For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
	  If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
            If both the HTTP and HTTPS versions
            return 200 OK and serve the same content:
              Replace HTTP with HTTPS.

 (Actually letting a shell for loop submit all this stuff for me.)

 If there are any URLs to be removed completely or at least not HTTPSified:
 Just clearly say so and I'll *undo my change*.

 If there are any valid, but yet not changed URLs:

 If you apply the patch, please let me know.

Applied, with a fix to the summary line, to match unicode contributions.
