  90 \r
  91 There are several other things that could also trip up this regexp.\r
  92 xtag:deletedx would be falsely matched, as would a quoted phrase\r
  93 containing "tag:deleted", while tag:"deleted" and tag:(deleted) would\r
  94 incorrectly not be matched.  Getting this right is hard, though I'd be\r
  95 happy with\r
  96 \r
  97   "\\<\\(tag\\|is\\):deleted\\>"\r
  98 \r
  99 or maybe\r
 100 \r
 101   "\\<\\(tag\\|is\\):\\(\"?\\)deleted\\>\\2"\r
 102 \r
 103 Implicit exclusions like this were actually one of my target features\r
 104 for the custom query parser, but I think hacking around that by\r
 105 inspecting the query string is a fine interim solution.  (One of these\r
 106 months I'll dust off the query parser, really!)\r
