[michael-o]

[MANDATORY] Describe the bug [MANDATORY]
When a default value with a space is passed along to includes the value is truncated from the first space char.

[MANDATORY] Bastille and FreeBSD version (paste bastille -v && freebsd-version -kru output)
0.10.20231125
13.3-STABLE
13.3-STABLE

[MANDATORY] How did you install bastille? (port/pkg/git)
pkg

[optional] Steps to reproduce?
(reduced from a larger setup)
Consider the following templates:

root@deblndw013x:/usr/local/bastille/templates
# cat sample/top/Bastillefile
ARG FIRST_DOMAIN="foo"
ARG SECOND_DOMAIN="bar"
ARG SEARCH_DOMAINS="${FIRST_DOMAIN} ${SECOND_DOMAIN}"

CMD echo "${SEARCH_DOMAINS}"
INCLUDE sample/bottom --arg SEARCH_DOMAINS="${SEARCH_DOMAINS}"
# cat sample/bottom/Bastillefile
ARG FIRST_DOMAIN="foo"
ARG SECOND_DOMAIN="bar"
ARG SEARCH_DOMAINS="${FIRST_DOMAIN} ${SECOND_DOMAIN}"

CMD echo "${SEARCH_DOMAINS}"

now let's run it:

# bastille template deblndw013x3j sample/top
[deblndw013x3j]:
Applying template: sample/top...
[deblndw013x3j]:
foo bar
[deblndw013x3j]: 0

[deblndw013x3j]:
Applying template: sample/bottom...
[deblndw013x3j]:
foo
[deblndw013x3j]: 0

Template applied: sample/bottom

Template applied: sample/top

# bastille template deblndw013x3j sample/top --arg FIRST_DOMAIN=baz --arg SECOND_DOMAIN="boo"
[deblndw013x3j]:
Applying template: sample/top...
[deblndw013x3j]:
baz boo
[deblndw013x3j]: 0

[deblndw013x3j]:
Applying template: sample/bottom...
[deblndw013x3j]:
baz
[deblndw013x3j]: 0

Template applied: sample/bottom

Template applied: sample/top

# bastille template deblndw013x3j sample/top --arg FIRST_DOMAIN=baz --arg SECOND_DOMAIN="boo" --arg SEARCH_DOMAINS="shmoo boo doo"
[deblndw013x3j]:
Applying template: sample/top...
[deblndw013x3j]:
shmoo boo doo
[deblndw013x3j]: 0

[deblndw013x3j]:
Applying template: sample/bottom...
[deblndw013x3j]:
shmoo boo doo
[deblndw013x3j]: 0

Template applied: sample/bottom

Template applied: sample/top

# bastille template deblndw013x3j sample/top --arg FIRST_DOMAIN=baz --arg SECOND_DOMAIN="boo" --arg SEARCH_DOMAINS2="shmoo boo doo"
[deblndw013x3j]:
Applying template: sample/top...
[deblndw013x3j]:
baz boo
[deblndw013x3j]: 0

[deblndw013x3j]:
Applying template: sample/bottom...
[deblndw013x3j]:
baz
[deblndw013x3j]: 0

Template applied: sample/bottom

Template applied: sample/top

As one can see if no SEARCH_DOMAINS is passed the default value has to kick in, but it is incorrectly processed. The passed value is passed through correctly.

[optional] Expected behavior
Pass down default ARG value with spaces
