Update installation instructions in README.md to use cat. Also add blank
lines at the end (instead of beginning) of template files, since they're
prepended (not appended) to existing files.
See difference of output between print and cat (zlogin having a blank
like at the end):
% print -rn "$(<zlogin)$(<test)"
#
# User configuration sourced by login shells
#
# Initialize zim
[[ -s ${ZIM_HOME}/login_init.zsh ]] && source ${ZIM_HOME}/login_init.zsh# Hello world
% cat zlogin test
#
# User configuration sourced by login shells
#
# Initialize zim
[[ -s ${ZIM_HOME}/login_init.zsh ]] && source ${ZIM_HOME}/login_init.zsh
# Hello world
Fixes#94. Fixes#280. Closes#300
This change allow arbitrary Zim location path by setting a new
environment variable, ZIM_HOME. If the user does not set it, Zim falls
back to the old "${ZDOTDIR:-${HOME}}/.zim" location.
Closes#203
