Re: BUG - *Matching rules won't match multiple tabs.

So, I ran this snippet:

editfiles:
    { /tmp/tabtest
        DeleteLinesMatching "REGEXGOESHERE"
    }

With the obvious substitution for the following:

^\t\t$                   (tab tab, the "\t" entries indicate "real"
tabs, not a literal '\' then 't'
^${tab}${tab}$       (tab tab)
^8${tab}${tab}$     (digit tab tab)
^8${tab}${tab}8$   (digit tab tab digit)
^  $                     (space space)
^${spc}${spc}$      (space space)

My sample file had lines with (spelled out in english...):

  only two tabs in it
  a space, then a tab
  a tab, then a space
  a space, then a space
  two tabs, then a digit
  a digit, then two tabs
  a digit, then two tabs, then a digit

Each one removed the lines I expected to be removed:  that is the
"space space" lines would remove only lines with 2 spaces.

Although not mentioned, I also tried these

  ^[:space:]+$
  ^[:blank:]+$
  ^[:space:]*$
  ^[:blank:]*$

but none of them worked at all. (I realize this is a tangent of sorts).

All testing was done using cfengine 2.2.0
