[elpa] externals/realgud 3904510 074/140: Large change to allow blacklisted files

[Rocky Bernstein]

branch: externals/realgud
commit 3904510df6d8ae9524465639c0e0b4a8780b6c95
Author: rocky <address@hidden>
Commit: rocky <address@hidden>

    Large change to allow blacklisted files
    
    ignore-re has been moved out of the loc struct and
    into the realgud-cmdbuf-info. It is now a list of regexps/strings
    which can be modified per debug session
