[DEYE-5] : regex with delimiters + SpotAndMargin function can mix results.

[aallali]

e.g of the problem:

• we have this text:
  "Lorem Lepsum 1337 Lorem Lepsum ;1337;"
• and this query --regex="(?<=;)(\d+)(?=;)"

the real number match here is the ;1337; with the ';' excluded
but when running SpotAndMarginfunc, i send the keyword that has been matched which is '1337'
the total match will be 1 but it will handle all '1337' inside the text as a match in order to apply the margin && highlight on it

Note: this bug doesn't affect the real number of matches, but just the output in screen which is highlighted
