BeforeBeginEnvironment not doing anything?

Question

I'm attempting to do something similar to Two column glossary, making an extant glossary style wrap into multiple columns. I've followed the suggestion in the comment to the first answer, i.e. use etoolbox to put the theglossary environment inside multicols. The problem is, only the AfterEndEnvironment seems to be doing anything. This code:

documentclass{article}
usepackage{glossaries}
    setacronymstyle{long-sc-short}
newacronym{acr}{acr}{Acronym}
makeglossaries
newglossarystyle{twocollong}{
    glossarystyle{long}
    BeforeBeginEnvironment{thegl‌​ossary}{begin{multicols}{2}}
    AfterEndEnvironment{theglossary}{end{multicols}}
    }
begin{document}
Text text 
acrshort{acr} 
text text

printglossary[style=twocollong]

end{document}

gives me the error that 'begin{document} is ended by end{multicols}'. Commenting out only the AfterEndEnvironment line (and leaving in BeforeBeginEnvironment) gives me a working document - no errors about begin{multicols} being ended by end{document}. It seems as if BeforeBeginEnvironment isn't inserting anything at all.

What am I doing wrong here?

The following defines a new glossary style based on mcoltree that produces a tabular-like appearance:

documentclass{article}

usepackage{glossaries}
usepackage{glossary-mcols}

makeglossaries

newlengthacrwidth

apptonewacronymhook{%
  settowidth{acrwidth}{textsc{theglsshorttok}}%
  addtolength{acrwidth}{1em}%
  ifdimacrwidth>glstreeindent
    setlength{glstreeindent}{acrwidth}%
  fi
}

setacronymstyle{long-sc-short}

newacronym{acr}{acr}{Acronym}
newacronym{acr2}{acr2}{Acronym2}
newacronym{acr3}{acr3}{Acronym3}
newacronym{acr4}{acr4}{Acronym4}
newacronym{acr5}{acr5}{Acronym5}
newacronym{acr6}{acr6}{Acronym6}
newacronym{acr7}{acr7}{Acronym7}
newacronym{acr8}{acr8}{Acronym8}
newacronym{acr9}{acr9}{Acronym9}
newacronym{acr10}{acr10}{Acronym10}

newglossarystyle{mystyle}{%
  setglossarystyle{mcoltree}%
  renewcommand{glossentry}[2]{%
    hangindentglstreeindentrelax
    parindent0ptrelax
    makebox[glstreeindent][l]{%
       glsentryitem{##1}glstarget{##1}{glossentryname{##1}}}%
    glossentrydesc{##1}glspostdescriptionspace##2par
  }%
}

begin{document}

Text text 
text text
glsaddall

printglossary[style=mystyle]

end{document}

Result:
