# A wrapper that injects the -w -M options into git blame commands.
# https://github.com/chrisdanford/BetterXcodeGitBlame/

# Xcode will pass arguments to git that look like:
#   ls-remote --heads
# or 
#   -c color.ui=false -c core.pager= -c core.quotepath=false --no-pager blame --no-color --line-porcelain -- SomeFile.m
# 
# We want to inject out extra flags into any `blame` command.
# We'll process each arg, inject our flags when we find the one `blame` (if any)
# and not inject once we see the `--` separator because everything after
# the separator are file names (and there could be legitimate files with 
# the name `blame`).
