htmlreport: Fix source view with leading empty lines

versat · versat · commit a6deae5f94c8 · 2020-01-21T09:13:55.000+01:00
For whatever reason, pygments removes leading empty lines by default.
This results in the error messages being in the wrong line, shifted by
how many empty lines were removed.
Adding the option "stripnl=False" as an option to the lexer constructor
avoids this issue.
