The performance issue must be caused by too many I/O requests to `conda.txt` from fgrep. This inline expansion should work to reduce # of read to the `conda.txt`. original performance: ``` % git rev-parse HEAD4f76be6a12% time bash -c 'pyenv rehash' bash -c 'pyenv rehash' 0.05s user 0.02s system 76% cpu 0.089 total ``` previous commit: ==> 4x slower than original ``` % git rev-parse HEAD4469d51ef7% time bash -c 'pyenv rehash' bash -c 'pyenv rehash' 0.06s user 0.03s system 25% cpu 0.358 total ``` with this workaround: ==> almost same as original ``` % git rev-parse HEAD 3ffe91bdbc69220eaecf6e2088229cc27366c3f3 % time bash -c 'pyenv rehash' bash -c 'pyenv rehash' 0.05s user 0.00s system 68% cpu 0.082 total ```
