MQL compiler script fails if filename or log message contain semicolons

[rosasurfer]

@see /bin/mqlc

• Splitting error messages fails if the message contains a ; semicolon.
• The bug also illustrates how the same problem will occur if the file name of the script itself contains a semicolon.

Bug:

$ mqlc TMA+CG-mtf.mq4

Use regexp similar to this (no splitting by semicolon). Untested.

line='2;94;C:\F\Projects\mt4\...;197:22;'\''=' - illegal assignment used'
if [[ $line =~ ^([^;]+);([^;]+);([^;]+);([^:]+):([^;]+);(.+)$ ]]; then
  lineno="${BASH_REMATCH[1]}"
  colno="${BASH_REMATCH[2]}"
  file="${BASH_REMATCH[3]}"
  line_in_file="${BASH_REMATCH[4]}"
  col_in_file="${BASH_REMATCH[5]}"
  msg="${BASH_REMATCH[6]}"
else
  echo "Parse error: $line"
fi
