           Summary: HTML_TINY_FONT too broad
           Product: Spamassassin
           Version: 3.1.8
          Platform: Other
        OS/Version: other
            Status: NEW
          Severity: normal
          Priority: P5

20_html_tests.cf:rawbody HTML_TINY_FONT /\<.*font\-size\:[ \"]*[01][^0-9]+.*\>/i
20_html_tests.cf:describe HTML_TINY_FONT        body contains 1 or 0-point font
50_scores.cf:score HTML_TINY_FONT 2.607 1.425 3.393 2.324


I'm seeing lots of FP related to HTML_TINY_FONT (score 3.4) driving the score
up. Either the score is too high or the pattern to broad. For example 

<div align="center" style="font-size:0.8em;">

is perfectly visible print, but triggers HTML_TINY_FONT. 

I would suggest refining the pattern. One possible would be

/\<.*font\-size\:[ \"]*(?:1pt|0(?:\.[01][0-9]*)?[^.0-9]+).*\>/i

The above should match

0pt
1pt
0em
0.0em
0.0123em
0.1em

while exclude

2pt    (is it readable?)
3pt    (is it readable?)
0.2em  (is it readable?)
0.8em  (readable)
