Improve regexes for log-file error and warning counts (fixed #797) #798
Match lines from the log file that have [ERROR] or [Warning] in them.
Including the square brackets in the regexes also simplifies other tests e.g. a Note that refers to the 'error log'.
NB The regexes could be further improved by removing the case-insensitive flag if the lines in the log file have always used the same capitalisation for 'ERROR' and 'Warning'.
I have looked at the MariaDB source-code for evidence of this, but as yet not found the truth.
