Reform and improve string literals (#793)
- Combine and simplify string and backtick lexing. - Allow newlines in strings and backticks. - Add triple-delimited indented strings and backticks. Common indented literal non-blank line leading whitespace is stripped. - If a literal newline is escaped, it will be suppressed. - Backticks starting with `#!` are reserved for a future upgrade.

Indented versions of both single- and double-quoted strings, delimited by triple single- or triple double-quotes, are supported. Indented string lines are stripped of leading whitespace common to all non-blank lines:
|
||||
|
||||
```make
|
||||
# this string will evaluate to `foo\nbar\n`
|
||||
x := '''
|
||||
foo
|
||||
bar
|
||||
'''
|
||||
|
||||
# this string will evaluate to `abc\n wuv\nbar\n`
|
||||
y := """
|
||||
abc
|
||||
wuv
|
||||
xyz
|
||||
"""
|
||||
```
|
||||
|
||||
Similar to unindented strings, indented double-quoted strings process escape sequences, and indented single-quoted strings ignore escape sequences. Escape sequence processing takes place after unindentation. The unindention algorithm does not take escape-sequence produced whitespace or newlines into account.

|

=== Ignoring Errors

Normally, if a command returns a nonzero exit status, execution will stop. To

Indented backticks, delimited by three backticks, are de-indented in the same manner as indented strings:
|
||||
|
||||
```make
|
||||
# This backtick evaluates the command `echo foo\necho bar\n`, which produces the value `foo\nbar\n`.
|
||||
stuff := ```
|
||||
echo foo
|
||||
echo bar

||||
```
|
||||
```
|
||||
|
||||
See the <<Strings>> section for details on unindenting.
|
||||
|
||||
Backticks may not start with `#!`. This syntax is reserved for a future upgrade.
|
||||
|
||||
=== Conditional Expressions
|
||||
|
||||
`if`/`else` expressions evaluate different branches depending on if two expressions evaluate to the same value:
