Subject: fix tahoe script installation logic
X-Git-Url: https://git.rkrishnan.org/components/com_hotproperty/%22doc.html/running.html?a=commitdiff_plain;h=ffeee54f9106f34d755cf0054efaf8f3278b3c20;p=tahoe-lafs%2Ftahoe-lafs.git

fix tahoe script installation logic

refine the logic in the .app which tries to install the 'tahoe' script.

now it will do nothing if 'tahoe' is found anywhere on the user's path,
and only if it's not present will it try to install it in each of the
candidate paths (/usr/local/bin ~/bin ~/Library/bin) which are on the
user's path
