[Bug 307011] [NEW] Sloppy regular expression handling in --exclude etc. causes --exclude tex to exclude text also.

[Cameron Kerr]

Public bug reported:

Binary package hint: debmirror

This bug affects all versions of debmirror available in Ubuntu and
Debian (although I have previously sent a patch to Debian)

When specifying --exclude tex to exclude the 'tex' section, the code
that formulates the regular expression does not anchor the beginning or
end, thus the 'text' section is also excluded. Upon further inspection
there are other options that this affects as well. Here is a patch
against debmirror:

782c782
<   $exclude =  "(".join("|", @excludes).")" if @excludes;
---
>   $exclude =  '^('.join("|", @excludes).')$' if @excludes;
784c784
<     "(".join("|", @excludes_deb_section).")" if @excludes_deb_section;
---
>     '^('.join("|", @excludes_deb_section).')$' if @excludes_deb_section;
786,787c786,787
<     "(".join("|", @limit_priority).")" if @limit_priority;
<   $include =  "(".join("|", @includes).")" if @includes;
---
>     '^('.join("|", @limit_priority).')$' if @limit_priority;
>   $include =  '^('.join("|", @includes).')$' if @includes;
